AC5300 Power

[Skynets]

Hello)

Somebody knows, how to know output power from this router?

earlier at me was ac3200 and these commands worked:
wl - i eth1 channels
wl - i eth1 txpwr_target_max
wl - i eth2 channels
wl - i eth2 txpwr_target_max
wl - i eth3 channels
wl - i eth3 txpwr_target_max

But now on ac5300 the answer doesn't come(

What commands need to be used?
